micro-projector for handheld devices

I just saw this article at about a tiny projector being built into handheld devices. I had this idea about an ipod projector in 2006 and did a sketch. Check out my old post:

3M to showcase a micro-projector for handheld devices at CES

The idea of stuffing a tiny projector into a handheld device isn't a new one -- we've seen a coupledifferent takes on the idea -- but it looks like it might be hitting the mainstream soon, as 3M has announced plans to demo a half-inch wide projection unit at CES that can put up a 40-inch image. The LCoS projector is about the size of a wireless headset, according to 3M, and tops out at VGA resolution -- which seems adequate, given the QVGA resolution of most handhelds. Apparently we'll be seeing devices with the projector built in later this year, and hopefully we'll get a chance to play with a couple at CES -- you'll know as soon as we do.

ST. PAUL, Minn.--(BUSINESS WIRE)--3M is now providing consumer electronics manufacturers with a revolutionary advancement in the emerging field of miniature projection technology. 3M scientists developed a breakthrough ultra-compact, LED-illuminated projection engine designed for integration into virtually any personal electronic device. Roughly the size of a wireless earpiece and less than half an inch thick, the 3M mobile projection engine delivers brilliant VGA resolution images and is available today.

With the expansion of digital media now accessible by mobile devices, consumers need the convenience of larger displays. 3M mobile projection engines achieve the size, efficiency, image quality and affordability needed for consumer adoption of this promising new product category, said Mike Kelly, executive vice president, 3M Display and Graphics Business. This development continues 3Ms long history as a global leader in advanced projection display technology. What is really exciting is that this technology is available now.

When deployed in a host platform, such as a mobile phone, 3Ms technology can project a 40-inch or larger image with no-speckle and a high-fill factor that ensures superior image quality. Each engine uses an advanced liquid crystal on silicon (LCOS) electronic imager in conjunction with proprietary 3M optics technology.

3M is partnering with leading consumer electronics companies that plan to launch products in early 2008. 3M Mobile Projection Technology will be shown in the Advanced Display Technologies Zone, booths 25727 and 25627, at the Consumer Electronics Show (CES), in Las Vegas, January 7-10, 2008.
